SPECIFICATION forming part of Letters Patent No. 627,528, dated June 27,1899. Application filed September 17, 1898. Serial No. 691,176. (Nomodel.)

To all whom it may concern:

Be it knownthat I, CHESTER PROUTY, a citizen of the United'States,residing at Ridgway,

in the county of Elk and State of Pennsylva nia, have invented certainnew and useful Improvements in Peavies; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in peavies of that class which aredistinguished from those devices disclosed in another ap plication (CaseA) filed by me September 13, 1898, and bearing Serial No. 690,877, owingto the fact that the pick and staff are driven orinserted in oppositedirections into a doublesocketed ferrule or band and one pick isreceived within a bore in thetapered tenon of said staff, thus makingthe implement relate to that class known as driven-pick peavies incontradistinction to, the implements in which the pick is Welded orunited firmly to the ferrule or band. In implements of this class asheretofore constructed it has been customary to make the staffina largeheavy piece and the band or ferrule of thin metal, uniform in thickness,and of just sufficient size to stand the strain of the pick and cantdog;but in the practical service of prior de-' vices it is found thatbesides being heavy, cumbersome, and unwieldy in the handset theoperator the pick is frequently broken off at the point where it joinswith the staff and ferrule, thus involving expense, delay, and annoyanceto the user. I aim to minimize these objections by a new constructionwhich increases the strength and durability at the juncture of the pickand staff at thehandle and in which all the parts contribute to the endof preventing the pick from working loose under the shrinkage of thewooden stafi during the drying of the staff in hot weather and otheratmospheric changes. I also aim to re duce the size of the implement andto bring the butt of the pivoted hook in exceedingly compact relation tothe staff andthe ferrule, thus promoting the convenience of the operatorin the manipulation of the implement; and a further object of theinvention is to provide durable and efficient front and back obviatewear on the wooden handle.

The invention consists in the construction and arrangement of parts,which will be hereinafter described, and pointed out in the claims.

A preferred embodiment of the invention is represented by theaccompanying drawings, forming a part-of this specification, in which-Figure 1 is a side elevation of a peavyembodying the presentimprovements. Fig. 2 is a longitudinal section of the device shown byFig. 1. Fig. 3 is a transverse section on the line a: as of Fig. 2. Fig.4 is a detail view of the ferrule or band removed from the staff. Fig. 5is a detail viewof the rolled sheet-steel blank invented by me for themanufacture of the ferrule or band shown by Fig. 4. Fig. 6 is a detailView of the rolled pick forming one of the improvements embraced by thepresent invention. Fig. 7 is a detail sectional elevation of the staff.Fig. 8 is a sectional elevation of a modified construction of the peavy.Figs. 9 and 10 are views of rolled metal and blanks contemplated by thisinvention, and Fig. 11 is a top plan View of a modified form of ferrule.

. Like numerals of reference denote like and correspondin g parts ineach figure of the drawings.

The staff or handle 10 is of peculiar form to receive one end of thepick 11, and it is thrust into a ferrule or band 12 to provide anexceedingly strong joint between the several elements to adapt theimplement to Withstand the strain at the point where the pick is mostexposed or subjected to breakage in the practical service of theimplement. This metallic ferrule or band 12 is one of the importantfeatures of my improved peavy, and while it may be cast of suitablemetal, such stops for the pivoted timber-hook which will as malleableiron, I prefer to roll it from sheetsteel to effect economy andexpedition in the which serves conjunctively with the pick in preventingthe latter from workingloose under shrinkage due to atmospheric changes.

5 and is designated by the numeral 14.. It

IOO The rolled metal blank is represented by Fig.

is rolled in flat form and tapered from a line m near one edge towardthe other edge, so that at the line 01. the metal is of less thicknessor gage than at the line m, and at the line 0 it is thinner than at thelines m it, while the blank is tapered in an opposite direction from theline m, thus giving the blank a double taper. This blank is alsoprovided at its thin edge with a series of lips or prongs 15, giving tothe blank a scalloped appearance; and it is furthermore provided at itsside edges with the flanges 16, which are divided by the incisions ornotches 17 from the edges of the blank beyond which the flanges 16protrude. form described, it is prepared for use by shaping it toconico-cylindrical form by bending the blank around a suitable form andwelding the beveled edges together, and then the flanges 16 are bent tolie radially to the longitudinal axis of the ferrule. In the process offorming the ferrule or band a thickened shoulder 18 is produced inadvance of the flanges to constitute a front stop for the pivoted hook,a flat metallic face 19 is formed between the flanges to serve as a backstop for said cant-dog, and a transverse slot 20 is made in the ferrulebetween the flanges to accom modate the eye-formed end of the log-hook21. The flanges 16 do not project or protrude from the face of theferrule for any considerable distance; but, on the contrary, they arenarrow, so as to occupy a compact relation to the ferrule, and by thisconstruction of the ferrule and by a notch or recess in the staff thebook has its heel arranged in compact relation to the ferrule and thestaff, so that the implement can be used with greater convenience by thelumberman in rolling different-sized logs. This cant-dog is formed atits heel with an eye 22, and it is arranged to flt between the flangesto pass through or work in the slot of the ferrule and to lie in oroccupy the notch or recess of the staff. This cant-dog is conneetedpivotally to the ferrule by a bolt 23, which passes through coincidentopenings in the flanges and the eye of the dog-heel, and this boltreceives a suitable nut. The front concave edge of the dog is formedadjacent to the eye-formed heel with a stop-shoulder 24, adapted toabutagainst the front stop-face of the ferrule, and the rear edge of thecantdog is arranged to bear against the back stopface of the ferrulewhen the hook is thrown backward, thus providing metallic bearingfacesfor the dog at the limits of the forwardand-backward throw.

The staff 10 is a single piece of wood having one end turned and boredto adapt it for union with the band or ferrule and the stem of the pick.To facilitate and cheapen the "manufacture of the implement and renderthe staffs interchangeable with the socketed ferrules or bands, I chuckeach staff in a turning machine or lathe and chuck and rim on one end ofthe staff a tapered tenon 26, and

The blank having been rolled in theafter removing the staff from themachine or lathe a tapered socket 27is bored into the tapered tenon ofthe staff.

The pick 11 is prepared from steel by rolling it to the proper contour,(shown by the drawings,) and this pick consists of the pick proper, 11,the shank or tang 28, and the shoulder 20. The pick has facets 30, whichare inclined and disposed at angles to make the pick present the taperedform square in cross-section. The tang 28 may be either round or angularin cross-section; but it is essential that it shall taper in a contrarydirection to the taper of the pick. The reverse tapers to the pick andthe tang result in the formation of the circumferential shoulder 29, andthis is increased by slight concavity or curvature of the tang, as at31, adjacent to 'the shoulder, thus making the facets of the pick moreprominent and well defined.

By producing the tapered metal blank and subsequently bending it toshape around a form the ferrule or band is provided with a taperedstaff-socket 32, and the metal of the band is made much thicker andstronger near the lower end, such metal tapering or decreasing from itsthickened end portion toward the large upper end of the socket portionof the ferrule or band. The socketed lower portion of the band flares,as at 33, from the thickened part in an opposite direction from thestaff-socket 32, and this flared part 33 of the ferrule-socket isadapted to receive the sloped intermediate part of the pick, so that theshouldered square pick is caused to bind firmly against the socket orsmall end of the ferrule. The tenon of the wooden staff terminates atthe socket 32 of the ferrule at the end of the flared portion 33 and theshouldered part of the pick, and thus the pick is adapted to havemetallic bearing against the ferrule, and its shank is wedged in thebored part of the staff. By wedging the tang in the bored end of thestaff and wedging the shouldered part of the pick against the end-of thesocket portion of the ferrule the parts are all intimately and solidlyunited together and prevent any tendency to work loose and the woodenstaff is prevented from shrinkage under atmospheric changes, thusobviating loosening of the pick. The joint is materially strengthened byincreasing the thickness of the metal forming the band at the pointwhere the square shoulders of the pick meets the ferrule and the staff,and the tendency of the staff to separate from the ferrule is furthercounteracted by the clenchable lips or prongs, which are provided at thethin upper edge of the ferrule and are bent over and embedded in thewood at a line above the beginning of the taper in the staff-tenon. At apoint intermediate of the length of said tapered tenon in the staff isprovided a notch or recess coincident with the slot in the ferrule orband, and it receives the heel of the pivoted cant-dog, so that thelatter may be pivoted close to the ferrule and the transverse diameterof the implement reduced within a narrow compass.

My improved construction enables the implement to be made smaller andlighter than the ordinary peavy of commerce, and at the same time theimplement is strengthened because the band or ferrule is thickened atthe point where the pick is exposed to the greatest strain and where thepick-tang and staff meet each other within the socketed band, thusadding stability to the implement at the place where the greatest strainis exerted thereon in the practical service of the tool.

The wooden staff is not liable to shrink in the socketed ferrule to suchan extent as to loosen the socket by shrinkage of the wooden staff,which has a tendency to tighten the pick, because the lower end of theferrule is closed by the shouldered pick, and the wood is thus partlyhoused and protected, and the joint between the ferrule and the pickobviates the formation of an abrupt enlarged shoulder at the reduced endof the ferrule. The hook lies in a compact relation to the ferrule andstaff, so'as to decrease the diameter of the implement, and the heel ofsaid dog is housed in the ferrule and the staff instead of projectingbeyond the staff, as is ordinarily the case.

Part of my improvements are applicable to cant-hooks. While I prefer tomake the ferrule long enough to accommodate both the pick and thecant-dog, I do not strictly confine myself to this particulararrangement, because the ferrule may be divided, as shown by Fig. 8. Theband 36 to fit over the end of the staff and receive the pick isseparate from the clip 37, which is secured around the. staff andreceives the heel and pivot-bolt of the cant-dog. This clip is rolledina single'piece, with the thickened edges 38 adapted to be bent to formthe flanges, and these flanges have bolt-holes to receive the bolt bywhich the clip may be clamped and the dog pivoted. The clip has a seriesof lips 39, adapted to be bent into the staff and serve to hold the clipfirmly in place on the' staff. The metal to form the clips may be rolledin a sheet or length, as shown by Fig. 10, which is to be shearedtransversely and then fashioned and bent to produce the clip, and thisconstruction enables the clips to be manufactured rapidly andeconomically.

I am aware that changes and alterations in the form and proportion ofparts and in the details of construction of the devices herein shown anddescribed as the preferred emspirit or sacrificing the advantagesthereof,

and I therefore reserve the right to make such modifications as fairlyfall within the scope of my invention.

I do not herein make any claim to novel fea i tures of the embodiment ofmy invention here mess-longitudinally in opposite directions from anintermediate point to provide the thickest part of the metal around thestafl at the narrowest portion of the socket, combined with a taperedand socketed staff fitted in the ferrule or band, and a shouldered pickwith a tang inserted in the ferrule and the staff, substantially asdescribed.

2. A peavy comprising a tapered conicocylindrical ferrule or band havingthe two oppositely-extending flared socket portions the adjacent ends ofwhich are at the thickest metallic section of the ferrule, apickprovidedwith the tapered tang and with the shoulder which is wedged inthe flared portion of the socketed ferrule, and a tapered and socketedstaff wedged in the ferrule and receiving the tang of the pick,substantially as described.

3. A peavy comprising a tapered conicocylindrical ferrule having theclenchable prongs at its upper edge, the flared socketed IOO positesides of the slot; a stafl having the tapered socketed tenon wedged intothe ferrule and provided with a notch which is coincident with the slotin the ferrule; a pick having the tapered tang and the shoulder betweenthe tang and pick and wedged into the flared thickened end of theferrule .for the tang to enter the stafi-socket, and a shoulderedcantdog having its heel fitted in the ferrule-slot and the staff-recessand pivoted to the flanges for its front shouldered edge and its backedges to bear against the stop-faces of the ferrule, substantially asdescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
